## Questions & Answers

**Q: Is this bold bright enough to read by on your nightstand like maybe a 40 W bulb would?**
A: Yes. My mom used one for reading - she is over 70. I would estimate the light is equal to between a 40W and 60W bulb. I use only one bulb to light everything in my great room (living room and dining room) and kitchen area at night. It's enough for everything I need to do.

**Q: How is this different from an ordinary light bulb with an orange coating that filters out blue light?**
A: Unlike many simply filtered lights the initial spectrum of the bulb is also adjusted so the while some of the blue is filtered what remains is a light still capable of rendering color sufficiently for our perception.

**Q: I work night's and have trouble sleeping during the day!  Would it help me?**
A: It has definitely helped me with being able to get to sleep when I want to. You have to make sure you don't have other sources of blue light as well (cell phone, monitor, TV, etc...).

**Q: Is this bulb dimmable?**
A: Yes, it's fully dimmable.
